Waves are difficult to describe and compare, so scientists often use models to explain them. In the culminating event, you will need to include a mathematical model to
explain how the device or phenomenon you choose demonstrates wave properties. How can you use mathematical models to represent different wave amplitudes or
frequencies? Think about what you use in math class to calculate different numbers for different situations.

Liquid from a brewery fermentation contains 10% ethanol and 90% water. part of the fermentation product (50,000 kg/h) is pumped to a distillation column on the factory site. under current operating conditions, a distillate of 45% ethanol and 55% water is produced from the top of the column at a rate of one-tenth that of the feed. what is the composition of the waste "bottoms" from the still?
